Acknowledgements

Much of the work presented here was conducted at the University of Leicester. It is a result of the author's dissertation, carried out within the MSc GIS and Archaeology (School of Archaeology and Ancient History, Department of Geography). The paper could not have been written without the technical assistance of Mark Gillings in GIS issues. I am also very grateful to him for reading and commenting upon a draft of this text, and for his help in the English editing; any errors remain my own. Nick Tate suggested
some crucial technical readings. I would like to thank Josep Guitart for his support of this project.
